Cyrillic Script
The Cyrillic script (/sɪˈrɪlɪk/ sə-RIL-ik) is a writing system used for various languages across Eurasia and is used as the national script in various Slavic, Turkic, Mongolic, Uralic, Caucasian and Iranic-speaking countries in Southeastern Europe, Eastern Europe, the Caucasus, Central Asia, North Asia and East Asia. (As of 2019), around 250 million people in Eurasia use Cyrillic as the official script for their national languages, with Russia accounting for about half of them. With the accession of Bulgaria to the European Union on 1 January 2007, Cyrillic became the third official script of the European Union, following the Latin and Greek alphabets. In the 9th century AD, the Bulgarian tsar Simeon I the Great – following the cultural and political course of his father Boris I – commissioned a new script, the Early Cyrillic alphabet, to be made at the Preslav Literary School in the First Bulgarian Empire, which would replace the Glagolitic script, produced earlier by Saints Cyril and Methodius and the same disciples that created the new Slavic script in Bulgaria. The usage of the Cyrillic script in Bulgaria was made official in 893. The new script became the basis of alphabets used in various languages, especially those of Orthodox Slavic origin, and non-Slavic languages influenced by Bulgarian. For centuries Cyrillic was used by Catholic and Muslim Slavs too (see Bosnian Cyrillic). Cyrillic is derived from the Greek uncial script, augmented by letters from the older Glagolitic alphabet, including some ligatures. These additional letters were used for Old Church Slavonic sounds not found in Greek. The script is named in honor of the Saint Cyril, one of the two Byzantine brothers, Saints Cyril and Methodius, who created the Glagolitic alphabet earlier on. Modern scholars believe that Cyrillic was developed and formalized by the early disciples of Cyril and Methodius in the Preslav Literary School, the most important early literary and cultural centre of the First Bulgarian Empire and of all Slavs. The school developed the Cyrillic script: The earliest datable Cyrillic inscriptions have been found in the area of Preslav. They have been found in the medieval city itself, and at nearby Patleina Monastery, both in present-day Shumen Province, in the Ravna Monastery and in the Varna Monastery. With the orthographic reform of Saint Evtimiy of Tarnovo and other prominent representatives of the Tarnovo Literary School (14th and 15th centuries) such as Gregory Tsamblak or Constantine of Kostenets the school influenced Russian, Serbian, Wallachian and Moldavian medieval culture. That is famous in Russia as the second South-Slavic influence. In the early 18th century, the Cyrillic script used in Russia was heavily reformed by Peter the Great, who had recently returned from his Grand Embassy in Western Europe. The new letterforms, called the Civil script, became closer to those of the Latin alphabet; several archaic letters were abolished and several letters were designed by Peter himself. Letters became distinguished between upper and lower case. West European typography culture was also adopted. The pre-reform forms of letters called 'Полуустав' were notably kept for use in Church Slavonic and are sometimes used in Russian even today, especially if one wants to give a text a 'Slavic' or 'archaic' feel.

Theodore Roosevelt National Park
Theodore Roosevelt National Park is an American national park comprising three geographically separated areas of badlands in western North Dakota. The park was named for U.S. President Theodore Roosevelt. The park covers 70,446 acres (110.072 sq mi; 28,508 ha; 285.08 km2) of land in three sections: the North Unit, the South Unit, and the Elkhorn Ranch Unit. The park's larger South Unit lies alongside Interstate 94 near Medora, North Dakota. The smaller North Unit is situated about 80 mi (130 km) north of the South Unit, on U.S. Highway 85, just south of Watford City, North Dakota. Roosevelt's Elkhorn Ranch is located between the North and South units, approximately 20 mi (32 km) west of US 85 and Fairfield, North Dakota. The Little Missouri River flows through all three units of the park. The Maah Daah Hey Trail connects all three units. The park received 708,003 recreational visitors in 2017. It is the only American national park named directly after a single person.

Masonry in the Context of Sustainable Buildings
The process of combining various parts to create a structure is called building. The most effective and significant component of any construction is masonry. The Colosseum, buildings from ancient Greece and Rome, Central American buildings, and Mycenaean structures all used this material as one of their primary building elements. The oldest form is dry masonry of irregularly shaped stones. The ecological qualities of masonry, as a restorative material with a low impact on the environment, as well as the environmental control capacity of the massive wall, bring masonry back to attention as a suitable material for sustainable building in the context of current concerns for sustainable architecture.

Impact of Nanoparticles on Plants under Drought Stress
Drought is a chronic abiotic stress affecting crop growth and development, accounting for approximately 70% of the potential loss of global crop yield and productivity. Drought hinders agriculture and forestry worldwide, due to very little rainfall or significant differences in moisture. The current trends of global warming are causing a major impact on the moisture levels of the soil and the environment, and are increasing the intensity of droughts. Plants are subjected to various stresses during their growth, and the morphology of plants is affected at all stages of development due to drought stress, with productivity losses expected to reach 30% globally by 2025.

Analytical Methodologies for Pharmaceuticals Determination in Biota Samples
There is increasing scientific evidence that some pharmaceuticals are present in the marine ecosystems at concentrations that may cause adverse effects on the organisms that inhabit them. Attempts have been made to optimize and validate analytical methods for the determination of residues of pharmaceuticals in marine biota by studying the stages of sample treatment, sample clean-up and subsequent analysis.

Medicine Lake Volcano
Medicine Lake Volcano is a large shield volcano in northeastern California about 30 mi (50 km) northeast of Mount Shasta. The volcano is located in a zone of east-west crustal extension east of the main axis of the Cascade Volcanic Arc and the Cascade Range. The 0.6 mi (1 km) thick shield is 22 mi (35 km) from east to west and 28 to 31 mi (45 to 50 km) from north to south, and covers more than 770 sq mi (2,000 km2). The underlying rock has downwarped by 0.3 mi (0.5 km) under the center of the volcano. The volcano is primarily composed of basalt and basaltic andesite lava flows, and has a 4.3 by 7.5 mi (7 by 12 km) caldera at the center. The Medicine Lake shield rises about 3,900 ft (1,200 m) above the Modoc Plateau to an elevation of 7,795 ft (2,376 m). Lavas from Medicine Lake Volcano are estimated to be at least 140 cu mi (600 km3) in volume, making Medicine Lake the largest volcano by volume in the Cascade Range (Newberry Volcano in Oregon has the second largest volume). Lava Beds National Monument lies on the northeast flank of the volcano. Medicine Lake Volcano has been active for 500,000 years. The eruptions were gentle rather than explosive like Mount St. Helens, coating the volcano's sides with flow after flow of basaltic lava. Medicine Lake is part of the old caldera, a bowl-shaped depression in the mountain. It is believed that the Medicine Lake volcano is unique, having many small magma chambers rather than one large one.

High Frequency Active Auroral Research Program
The High Frequency Active Auroral Research Program (HAARP) was initiated as an ionospheric research program jointly funded by the United States Air Force , the U.S. Navy, the University of Alaska Fairbanks, and the Defense Advanced Research Projects Agency (DARPA). It was designed and built by BAE Advanced Technologies (BAEAT). Its original purpose was to analyze the ionosphere and investigate the potential for developing ionospheric enhancement technology for radio communications and surveillance. As a university-owned facility, HAARP is a high-power, high-frequency transmitter used for study of the ionosphere. The most prominent instrument at HAARP is the Ionospheric Research Instrument (IRI), a high-power radio frequency transmitter facility operating in the high frequency (HF) band. The IRI is used to temporarily excite a limited area of the ionosphere. Other instruments, such as a VHF and a UHF radar, a fluxgate magnetometer, a digisonde (an ionospheric sounding device), and an induction magnetometer, are used to study the physical processes that occur in the excited region. Work on the HAARP facility began in 1993. The current working IRI was completed in 2007; its prime contractor was BAE Systems Advanced Technologies. As of 2008, HAARP had incurred around $250 million in tax-funded construction and operating costs. In May 2014, it was announced that the HAARP program would be permanently shut down later in the year. After discussions between the parties, ownership of the facility and its equipment was transferred to the University of Alaska Fairbanks in August 2015. HAARP is a target of conspiracy theorists, who claim that it is capable of "weaponizing" weather. Commentators and scientists say that advocates of this theory are uninformed, as claims made fall well outside the abilities of the facility, if not the scope of natural science.

Climate Change in the Caribbean
Anthropogenic climate change is caused by the rapid increase of greenhouse gases in the atmosphere principally from burning fossil fuels, converting forestland to pasture and monoculture cropland, with the greatest contributions happening in the period since the Industrial Revolution. Climate change could pose disadvantageous risks to the islands in the Caribbean. The environmental changes expected to affect the Caribbean are a rise in sea level, stronger hurricanes, longer dry seasons and shorter wet seasons. As a result, climate change is expected to lead to changes in the economy, environment and population of the Caribbean.

Neuroarchaeology
Neuroarchaeology refers to a field of study that records neuroscientific history through archaeological methods of investigation. The term was first suggested and thus coined by Colin Renfrew and Lambros Malafouris first individually in 2004 and then collaboratively in 2008.It is a combination of the words "neuro-" from 'neuroscience' indicating its connection with the brain sciences and "archaeology" meaning study of human history and prehistory through excavations and other tools. Significant leaps in brain and cognitive sciences in the 21st century have opened up new areas of partnership between archaeology and neuroscience. This collaboration can help an archaeologist figure out biological and neural substrates of human cognitive abilities present in the archaeological objects. The knowledge of neuroscience can also be applied to critically review and challenge existing theories and assumptions about the inception of modern human cognition. The term implies a new area of research that could investigate issues relating to the collaboration between the brain and culture over the long term development of humans. So far, the goals of neuroscience and archaeology are the same- to understand human nature. But their disciplinary approaches diverge significantly. Neuroarchaeology aims at building the analytical bridge between brain and culture ""by putting material culture, embodiment, time and long-term change at centre stage in mind".
